YouTube has 800 million videos and generates over 500 hours of new content every minute. For researchers, content creators, and AI developers, that’s an extraordinary corpus of structured information — titles, descriptions, metadata, transcripts, comments.
Getting at it systematically is where the friction starts.
The problem with YouTube’s official API
YouTube Data API v3 exists and is actually usable — but it has limitations:
- Quota: 10,000 units/day by default (a channel list request costs 1 unit, a video details request costs 1–3, a search costs 100)
- Transcripts: not available via the official API at all
- Comments: available but paginated and rate-limited
- Raising quota requires manual review and can take weeks
For bulk enrichment, competitive research, or AI training data, you’ll hit the wall fast.
What YouTube workers extract
From a video:
- Title, description, duration, publish date
- View count, like count, comment count
- Channel name, channel ID, subscriber count
- Tags, category, language
- Transcript (full, timestamped, or plain text)
From a channel:
- All videos (up to a specified limit)
- Subscriber count, total views, video count
- Channel description, links, creation date
From a search query:
- Top N videos matching the query
- All metadata fields above for each result
Extracting a transcript
curl -X POST https://api.seek-api.com/v1/workers/youtube-transcript/jobs \
-H "X-Api-Key: YOUR_KEY" \
-H "Content-Type: application/json" \
-d '{"videoUrl": "https://www.youtube.com/watch?v=dQw4w9WgXcQ", "format": "plain"}'
Response:
{
"videoId": "dQw4w9WgXcQ",
"title": "Rick Astley...",
"duration": 212,
"transcript": "We're no strangers to love. You know the rules and so do I...",
"language": "en",
"segments": [
{"start": 0.0, "end": 3.4, "text": "We're no strangers to love."},
{"start": 3.4, "end": 6.1, "text": "You know the rules and so do I."}
]
}
Set "format": "segments" to get the full timestamped array for subtitle-style output.
AI use cases for transcripts
Once you have transcripts, the possibilities are wide:
Summarization: Feed the transcript to GPT-4o and extract a 3-sentence summary for a newsletter or content digest.
Q&A extraction: Parse transcripts of tutorial videos to build FAQ databases or knowledge bases.
Training data: Collect domain-specific transcripts (legal, medical, technical) to fine-tune models.
Keyword mining: Identify recurring phrases and topics across a channel to find what resonates with an audience.
Multilingual content: Detect transcript language, translate, and republish in new markets.
Channel analysis pipeline
Analyze a competitor’s full YouTube channel:
import httpx, time
VIDEO_LIMIT = 50
# Step 1: Get all videos
job = httpx.post(
"https://api.seek-api.com/v1/workers/youtube-channel/jobs",
headers={"X-Api-Key": API_KEY},
json={"channelUrl": "https://www.youtube.com/@MrBeast", "limit": VIDEO_LIMIT}
).json()
# Wait for result
while True:
status = httpx.get(f"https://api.seek-api.com/v1/jobs/{job['job_uuid']}", headers=...).json()
if status["status"] == "completed":
videos = status["result"]["videos"]
break
time.sleep(5)
# Step 2: Get transcripts for all videos
transcript_jobs = []
for v in videos:
j = httpx.post(
"https://api.seek-api.com/v1/workers/youtube-transcript/jobs",
headers={"X-Api-Key": API_KEY},
json={"videoUrl": v["url"]}
).json()
transcript_jobs.append(j["job_uuid"])
In one pipeline, you now have 50 transcripts from a competitor channel — structured, searchable, ready for any downstream analysis.
Comment extraction for sentiment analysis
YouTube comments are a goldmine for product feedback, audience opinion, and social listening:
POST /v1/workers/youtube-comments/jobs
{
"videoUrl": "https://www.youtube.com/watch?v=...",
"limit": 200,
"sort": "top"
}
Feed the top 200 comments into a sentiment classifier to instantly understand how a piece of content was received.
Cost breakdown
| Task | Credits | Approx. USD |
|---|---|---|
| Single video + transcript | 2 | $0.004 |
| Channel crawl (50 videos) | 10 | $0.02 |
| 50 transcripts | 50 | $0.10 |
| Full channel analysis (50 videos + data + transcripts) | ~65 | ~$0.13 |
A complete competitive analysis of a rival’s top 50 videos costs about 13 cents.
